Window / Re: RenderWindow not appearing?

« on: November 17, 2012, 07:38:48 pm »

Thanks for the hints, guys!  I've switched to using the SFML 2.0 RC build, and that's solved my problem.  Now I can get down to the fun stuff.

@cire -- Sorry, I definitely missed those.  I'll spend more time searching next round.

Window / RenderWindow not appearing?

« on: November 11, 2012, 11:49:06 pm »

I am attempting to follow a video tutorial, and I've run into an strange runtime issue. 

I have my project set up, I and am able to compile and run.  But I am not able to see the RenderWindow on my screen.  All I can see is an empty console window pop up.  No compile errors and no linker errors are mentioned in the build log.  What am I missing?

I am trying to follow along at 6:14 location in the tutorial below:


In the video at 6:14, you can see he has two windows open: the black console window, and another blue-ish window (which I assume is the RenderWindow).  When I build and run, I see the black console window, but the blue window never appears.

Environment:
Windows 7 Professional 64-bit
Code::Blocks + MinGW
SFML 1.6, dynamically linked

I do have an ATI video card - I've heard that ATI doesn't play well with SFML, but I haven't seen any specific references to my issue in regards to ATI.

Here's the code I am trying to run:

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
sf::RenderWindow window(sf::VideoMode(800, 600, 32), "SFML Sample Application");

while(window.IsOpened())
{
sf::Event event;
while(window.GetEvent(event))
{
switch(event.Type)
{
case sf::Event::Closed:
window.Close();
break;
}
}

window.Clear();
window.Display();
}

return 0;
}
Any ideas?

General / Re: SFML 1.6 Tutorial: undefined reference to `_imp___ZN2sf5ClockC1Ev'

Figured it out!  I thought it would be something stupid, and it was. 

I was linking against the the wrong library build.  I had originally downloaded the Visual Studio C++ build of SFML, as I was going to get things up and running in that environment.  But when I switched over to Code::Blocks+MinGW, I didn't re-download the proper development files, I had just re-used the Visual Studio build files.  As soon as I grabbed the MinGW files and set them up in Code::Blocks, the linker was happy.

General / SFML 1.6 Tutorial: undefined reference to `_imp___ZN2sf5ClockC1Ev'

« on: November 11, 2012, 03:47:43 am »

I am having trouble completing the tutorial to set up SFML 1.6 with CodeBlocks+MinGW (http://www.sfml-dev.org/tutorials/1.6/start-cb.php).  Specifically, when I build the project I get the following build log:

-------------- Build: Debug in sfmlTest ---------------

Compiling: main.cpp
Linking console executable: bin\Debug\sfmlTest.exe
obj\Debug\main.o: In function `main':
C:/Dev/codeBlocksTest/sfmlTest/main.cpp:6: undefined reference to `_imp___ZN2sf5ClockC1Ev'
C:/Dev/codeBlocksTest/sfmlTest/main.cpp:9: undefined reference to `_imp___ZNK2sf5Clock14GetElapsedTimeEv'
C:/Dev/codeBlocksTest/sfmlTest/main.cpp:10: undefined reference to `_imp___ZN2sf5SleepEf'
C:/Dev/codeBlocksTest/sfmlTest/main.cpp:7: undefined reference to `_imp___ZNK2sf5Clock14GetElapsedTimeEv'
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 0 seconds)
4 errors, 0 warnings

It looks like a problem with my linker configuration, but I've combed through the tutorial a dozen times now and I can't see what I am doing wrong or missing.  As far as I can tell, I am following the instructions to the letter.  I've set up the Global Compiler Settings >> Search Directory >> Compiler and Linker to point to the appropriate SFML include and lib directories.  I've updated my project build options (for both Debug & Release) to include the -lsfml-system library.  I've added the compiler SFML_DYNAMIC define as well (again, in both Debug & Release targets).  I have verified that all of the directory path settings are valid; I copy & pasted all of them into Windows Explorer to verify.  I also copy & pasted the code straight from the tutorial:

Code: [Select]

#include <SFML/System.hpp>
#include <iostream>

int main()
{
    sf::Clock Clock;
    while (Clock.GetElapsedTime() < 5.f)
    {
        std::cout << Clock.GetElapsedTime() << std::endl;
        sf::Sleep(0.5f);
    }

    return 0;
}
I searched around, and did see a couple people with similar issues:
http://en.sfml-dev.org/forums/index.php?topic=6900.msg45530#msg45530
http://www.cplusplus.com/forum/beginner/49533/

But their solutions have not resolved my errors.  I try a full Clean + Rebuild after each change I make as well.

I've verified that I am using the GCC 4.4 compiler:

C:\Program Files (x86)\CodeBlocks\MinGW\bin>gcc --version

Thanks to everyone who takes a look.  If any further information would be helpful, just let me know, and I'll put together whatever I can.
